POWER GENERATOR.

Application filed April 21,

T 0 (all whom it may concern:

Be it known that I, OSBORNE H. Parsons, a subject of the King of Great Britain, residing at Halifax, in the Province of Nova Scotia, Canada, have invented certain new and useful Improvements in Power Generators, and do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable'others skilled in the art to which it-appcrtainsto make and use the same.

The present invention relates to new and useful improvements in power generators, and more particularly to a mechanism for generating power through the rolling motion of .a boat, or any other suitable floating object of sufficient size.

An object of the invention is the provision of a mechanism whereby the rolling or rocking motion of a boat can be utilized for generating power, through a generator, and other suitable means for charging batteries or the like from which suitable apparatus can be operated, for driving or propelling a boat.

Another object of the invention, is the provision of an apparatus so constructed that it can be mounted, either to the stern Or at the side of a boat, and by the rolling or plunging movement thereof, generate suflicient power to propel the boat as desired, through other employed mechanism.

Still another object of the invention is the provision of a mechanism as above referred to, which is actuated by the rocking or rolling motion of a boat, and which may be applied either singly or in series, for the purpose of generating power, through suitable mechanism to charge the batterles WlllCll supply current to the driving or propelling means of the boat.

A further object of the invention is the provision of a device of the above specified character, which includes a suitable rocklng lever, so designed as to impart a rotary motion to a shaft, adapted for driving a generator or other suitable device to generate power, for the purpose of driving the boat, but it is to be understood that it may be connected directly to the propelling means of the boat if preferred.

A still further object of the invention is the provision of an apparatus such as above referred to, which will be comparatively simple and inexpensive to manufacture, re-

liable and ellic-ient in use, and readily operated.

lVith the above and other objects in view, the present invention resides in the novel features of construction formations, combinations, and arrangements of parts, to be hereinafter more fully described, claimed,-

and illustrated in the accompanying drawings, forming a part of the present appli cation and in which,

Figure 1 is a side elevation of the invention;

Figure 2 is a transverse sectional view, taken through Figure 1;

Figure is a similar view taken on a different plane through Figure 1;

Figure 4 is a view similar to Figure 2, showing the device in tilted position;

Figure 5 is a face view, showing the clutch mechanism; and,

Figure 6 is a transverse sectional view thereof.

Referring, now to the accompanying drawings, by corresponding characters of reference throughout the several views, the numeral 10 designates in general, a base to the upper side of which are bolted as shown at 11. a plurality of parallel upwardly extending A-shaped frames 12, 13 and 14, which have connected to their upper edges, a spacing bar 15, which holds them rigidly in the position shown in Figure 1. A drive shaft 16 is journalled, in the upper portion of the frames 12, 13 and 14: extending parallel to the bar 15, while journalled in the lower portion of said frames is a pair of parallel spaced counter shafts 17, which are disposed in parallel relation to the before described shaft 16.

A supplemental counter shaft 18 is journalled between the frames 13 and 14 and positioned between the shafts 16 and 17, while a power shaft 19 is likewise journalled between the frames 13 and 14:, and spaced between the shafts 16 and 18 A rocker lever 20 is keyed to the shaft 16 and projects through a slot 21, formed in the base 10. This lever 20 has secured to its lower end by brackets 22, a suitable bucket 23 which is so constructed that it may receive any desired weighted substance to regulate the weight of the lever, in order that the machine might be most successfully operated.

A rocker head 24 having oppositely extending arms 25 is keyed to the shaft 16, so that. the said arms 25, may be normally disposed in a horizontal. position.

Links 26 are pivotally connected to the ends of the arms 25, at their upper ends, and at their lower ends as at 27-, tothe arm 28, carried by the counter shafts 17 Obviously upon the rocking movement of the lever 20, a rotary motion will be imparted to the before described shafts 17.

Gears 29 are keyed tothe shafts 17 and mesh with a gear 30 which is carried by a stub'shaft -31, 'journalled in the frames 13 and let in the same horizontal plane and between the shafts 17.

This obviously imparts a rotary motion to the said stub shaft 31 which has also keyed thereto a larger gear 32 which meshes with a pinion 33, keyed to the shaft 18.

A larger gear 34: is also keyed to the shaft 18 which meshes with the pinion 35, keyed to the power shaft 19. This shaft 19 is provided with a suitable fiy wheel 36, and also a drive pulley 37, over which a belt or the like (not shown) may be positioned for the purpose of imparting power, from the shaft 19, to the generator or other suitable device. (not shown) which may be actuated by the machine.

I11 use the apparatus above described, may be positioned either on the stern or the side of the boat, to obtain its power from either the plunging or rolling motion of the boat or if preferred two of such apparatus, may

' be applied, one at the stern, and one at the side of the boat, for utilizing both the rolling and plunging motion, for generating power.

In order to provide for rotation of the shafts 17, in one direction only, a suitable clutch mechanism is provided for the gears 29, indicated by the numeral 28. In this form the faces of the gears 29 are countersunk at 40, to receive the disks 89 which are keyed to the shafts 17. The edges of the disks are cut away at intervals forming cam surfaces 11 which taper in like direction from one end to the oppositeends thereof. Rollers 12 are positioned between the cam surfaces L1 and the inner peripheries of the sunk portions 4L0, of the gears 29, and are normally drawn towards the major end of the cut out portions of ,the disks by the springs 4-2. hen the shafts 17 turn in a clock-wise direction, in Figure 5, the gears 29 will be rotated therewith, but when the latter turn in the opposite direction, the said gears will remain loose upon the disks 39 and are prevented from turning therewith.

This arrangement provides for movement of the gears upon rotation of the shafts 17 in one direction only, and the rocking motion will not serve, to turn the gears first in one direction and then the other.

From the foregoing description, taken in connection with the accompanying drawings, it will be manifest that a mechanism for imparting power, to a generator or the like, through the rocking motion of a boat, is provided which will fulfil all of the necessary requirements of such a device, and it should be understood in this connection, that various minor changes in the specific details of construction, can be resorted to within the scope of the appended claims,

without departing from the spirit or sac-' rificing any of the advantages of the invention.

Having. thus fully described the invention, what I claim as new and desire to secure by Letters Patent .is:

1. In a device such as described, the combination with a boat or the like of a plurality of frames, mounted thereon, a drive shaft journalled in said frames, counter shafts mounted in said frames, means for imparting rotary motion from the drive shaft to. thecounter shafts, a supplemental counter shaft, interposed between the counter shafts and the drive shaft, and means for imparting power from the main counter shafts, through the supplemental counter shaft, to the power shaft.

2. The combination in a device of the character described of a plurality of frames, a drive shaft mounted therein, a rocking lever secured to the drive shaft, a bucket attached to the rocking lever, rocker arms attached t0 the drive shaft, counter shafts mounted in the frames, arms attached to the counter shafts, links connecting the rocker arms to the arms carried by the counter shafts, a power shaft, and means for imparting rotary motion from the counter shafts to the ower shaft.

3. The com ination in a device such as described, with a boat or the like, of a plurality 'of frames, a. drive shaft mounted.

therein, a rocking lever attached to said drive shaft, rocker arms extending from the drive shaft, counter shafts mounted in said frames, arms extending from the counter shafts, links connectin the rocker arms to the arms extending from the counter shafts, a power shaft, and gears interposed between the counter shafts, and a power shaft, for imparting rotary motion to the latter.

In witness whereof I have hereunto set my hand. V OSBORNE HAVELOCK PARSONS.
